Or just recievers for Elinchrome/Profoto/Walimex/Bowens or other brands. Elinchrome has some studioheads with build-in recievers for their Skyport-system. Would it be a big problem to make recievers that could communicate with a studio-head - set the output and use the cameras light-meter (without leak, or without hair-light pointed at the display couldn't resist) ?
